I've seen about 30% of what is written in your essay on other essays on capital punishment on here, in which I'm guessing you're all getting it from the same source and not all of which is copied is also being cited. As I've also suggested to another, you should compare the United States with other countries, such as its close neighbour, Canada. China would also be interesting. Also, I don't think publically showcasing the death penalty will deter criminals. The United States executed much more people in its earlier days and obviously crime was still prevalent then. I wouldn't say you've proved capital punishment is true justice, either.
